Suspect had been refusing to come out of home on Collingwood Street

Detroit police say a suspected gunman surrendered Tuesday morning after roughly a three-hour standoff in a home on the city's west side.

Detroit Police Commander Elvin Barren said the situation started around 4 a.m. with an argument between the suspect and his girlfriend in the 2700 block of Collingwood Street.

Barren said the girlfriend found another female in the home and a dispute broke out. The girlfriend said the suspect scratched her on the neck and then fired a shotgun into the air. No one was hurt, but the boyfriend then refused to come out of the home for police.
